The custom 45mm drivers deliver a pure, uncolored sound directly from the transducer with a 5-40,000 Hz frequency response, avoiding acoustic resonance for minimized distortion. At just 199 grams, the redesigned headband and breathable open-back earcups provide a featherlight fit that virtually disappears during long sessions. This headphone is best for mixing and mastering engineers who require an accurate, spacious soundstage for critical, detail-oriented work.
